Yes (though I couldn't have told you that without experimenting -- I
always assumed it checked whole lines).

That is a bit harder, and AFAIK not possible with -S. You could always
post process the log output. E.g.,:
git log -p | perl -ne '
BEGIN { $/ = "commit " }
chomp; print if /^\+import /
'
which lets you get quite fancy with the matching.

The usual question (for me, anyway) is "when did X get introduced?" when
looking for a token.
